Definitions
- the present invention relates to a cap for a container with a neck, of the type comprising a body which can be fixed in leaktight manner to the neck of the container and in which is formed at least one conduit for emptying the container, and a valve blocking said conduit.
- the present invention also relates to a container provided with such a stopper.
- Patent FR-2 687 130 describes a closure device for a bottle, which consists of only two elements, both in the form of a cap.
- One of the two elements or inner cap, in service, covers the neck of the bottle and is tightly fixed to it, while the other element or outer cap covers the inner cap and can rotate relative to that -this around an axis coincident with the axis of the neck of the bottle.
- a chamber is provided between the upper walls of the two caps.
- the upper wall of the outer cap is made in the form of a thin wall so as to form an elastic membrane, and it is curved in the direction of the upper wall of the inner cap.
- the elastic membrane In its center the elastic membrane has an orifice in which s engages a boss formed in the center of the upper face of the inner cap, so as to seal the central orifice of the elastic membrane.
- the upper wall of the inner cap has two eccentric holes, which are formed on either side of the central boss and in which two bosses engage in corresponding position on the underside of the elastic membrane, so as to seal these two orifices.
- this substance will stagnate between the skirts of the two caps throughout the duration of use of the bottle. Not only is this unhygienic, especially for food substances, but also the substance included between the skirts of the two caps can cause the two caps to stick together, thus making subsequent opening of the closure device very difficult. , or even impossible.
- the closure device must then be closed by exerting pressure on the elastic membrane in order to return it to its concave state. If this operation is carried out with a finger of the hand, this is contrary to the hygiene or can be dangerous if the bottle contains a substance, for example a toxic or corrosive substance, which should not be touched with the fingers of the hand.
- the stopper device of the patent FR-2 616 756, as with the stopper of patent FR-2 687 130 it is impossible to fill the bottle without having previously removed the stopper or stopper device.
- the valve incorporates into the cap of patent FR-2,687,130, like the elastic membrane of the plugging device of patent FR-2,616,756 allow flow only from the inside to the outside. from the bottle. Consequently, if special precautions or restrictive measures are not adopted when filling the bottle, the filling substance is in contact with the surrounding air throughout the filling period and until the stopper or device stopper is placed on the neck of the bottle.
- the present invention therefore aims to remedy the aforementioned drawbacks of the plugs or known plugging devices described above.
- the stopper according to the invention is characterized in that the body of the stopper comprises a cylindrical part intended to be engaged in the neck of the container and having in its cylindrical surface a groove which extends circumferentially over at least one part of the circumference of said cylindrical portion, in that the conduit comprises a first and a second channel which are separated from one another, extend in the cylindrical part of the body e "t open, at one their ends, in said groove respectively by first and second orifices which are spaces apart from each other in the circumferential direction of the groove, the first channel emerging, at its other end, through a third orifice situated in a first surface of end of the body which, in service, is inside the container, the second channel opening, at its other end, through a fourth orifice located in a second end surface of the body rps which, in service, is outside the container, and in that the valve is formed by a membrane of elastomeric material which tightly encloses the cylindrical part of the body and the surface of the groove by covering the first and
- the plug according to the invention can advantageously be made in one piece by a known technique of bi-inj ection molding.
- the plastic material intended to form the body of the plug and the elast ⁇ mère material intended to form the membrane can be injected into the mold successively or simultaneously depending on whether one or the other of the known bi-injection molding techniques is used.
- a cap can be added to the cap according to the invention.
- the cap has a nozzle and it is rotatably mounted on the body of the cap so that, in a first position of rotation of the cap, the internal channel of the nozzle is in correspondence with the second channel of the body of the cap. and that, in a second position of rotation of the cap, the internal channel of the nozzle is not in concordance with the second channel of the body, so that this second channel is closed by the cap.
- the above-mentioned cap will preferably be added to the stopper when a certain pressure inside the container is permanently prevalent, for example when the latter contains a carbonated drink or a fluid substance and a propellant gas.
- the stopper according to the invention optionally provided with its cap, can be used with containers having the most diverse structures and shapes and containing the most diverse fluid substances, provided that the receptacles are provided with a neck.
- the stopper according to the invention it is possible, for example, to use, as a container, a bottle or a vial, made of metal, glass or a rigid or semi-rigid plastic material, a pocket or a bladder made of a flexible material, etc.
- the stopper and its cap can be mounted on a container whose internal volume can vary from a value corresponding to the nominal capacity of the container to a value almost zero.
- a container with variable volume can for example be constituted by a pocket or a bladder of flexible plastic material or by a bottle whose body is shaped like a compressible bellows and extendable in the longitudinal direction of the bottle, as by example the bottle described in the patent application in France filed the same day as the present patent application, in the name of the same Applicant, and having as title: "bottle with variable volume in plastic material".
- the container When the stopper according to the invention is mounted on such a container with variable volume, previously put in a state or its internal volume is zero, the container can then be filled through the channels of the stopper without the substance introduced into the container is in contact with the surrounding air, and the container can then be emptied without air entering the container. This is particularly advantageous for the good conservation of the substance contained in the container and / or when the latter must maintain a high degree of sterilization.
- FIG. 1 is a view, in partly in elevation and partly in section, showing a plug according to a first embodiment of the invention, the plug being shown engaged in the neck of a container which is only partially shown;
- Figure 2 is a side view of the plug along arrow F of Figure 1;
- Figure 3 is a top view of the cap of Figure 1;

- Figures 10 to 12 are sectional views of the cap, respectively along lines XX, XI-XI and XII-XII of Figure 8;
- Figures 13 and 14 are sectional views showing the cap of Figures 1 to 6 and the cap of
- the plug 1 shown in Figures 1 to 6 is constituted by a plastic body, for example a polyurethane having a Shore A hardness between
- the body of the plug 1 comprises a cylindrical part 1a and a spherical head 1b molded in one piece.
- the center of the spherical head 1b is located on the axis 10 of the cylindrical part 1a.
- the cylindrical part 1a of the body is intended to be engaged in the neck 2a of a container 2 (FIG. 1) and its diameter is therefore dimensioned accordingly.
- a groove 3 is formed in the peripheral surface of the cylindrical part la. In the embodiment shown, the groove 3 extends all around the cylindrical part la, but it could extend only over part of the circumference of the cylindrical part la
- a first channel 4 is formed in the cylindrical part 1a and opens, at one end, into the groove 3 by an orifice 4a and, at its other end, in the lower end face 1c of the body of the stopper by another orifice 4b .
- a second channel 5 is formed in the body of the plug 1.
- the second channel extends obliquely in the cylindrical part la and in the spherical head 1b and it opens, at one end, in the groove 3 through an orifice 5a and, at its other end, into the outer surface of the spherical head 1b through an orifice 5b.
- the orifices 4a and 5a are spaces from one another in the circumferential direction of the groove 3, as shown in FIGS. 1 and 2.
- the groove 3 could extend over a circular arc whose length corresponds to the angular distance between the two orifices 4a and 5a.
- the orifice 5b of the channel 5 is preferably located in the upper half of the spherical head 1b and is not located on the axis 10 of the cylindrical part 1a of the body of the plug.
- the cylindrical part 1a of the body of the stopper, covered of the membrane 6, has an outside diameter very slightly larger than the inside diameter of the neck 2a of the container 2 (FIG. 1), so that the plug 1 can be fixed to the container 2 by wedging its cylindrical part la in the neck 2a
- the cap could be provided with a cylindrical skirt surrounding the neck 2a and fixed to it by clipping or by screwing, said cylindrical skirt being connected in one piece to the body of the cap in the transition zone between the cylindrical part 1a and spherical head 1b.
- the membrane 6 plays the role of a valve which, at rest, closes the orifices 4a and 5a.
- the filling of the container 2 with a fluid substance can be carried out by injecting said substance under pressure into the channel 5 through the orifice 5b.
- the substance under pressure repels the elastic membrane 6 in the region of the orifice 5a, which has the effect of opening this orifice. Then, the substance circulates in the throat 3 Up to the orifice 4a or it enters the channel 4, then flows into it to enter the container 2 through the orifice 4b.
- the substance can, by elastically deforming the membrane 6, follow a reverse course of the course described above, to exit the plug through the orifice 5b.
- the membrane 6 resumes its initial shape elastically and again closes the orifices 4a and 5a.
- the valve formed by the membrane 6 therefore allows both filling and emptying of the container 2.
- the fluid substance in order to pass from channel 5 to channel 4, or vice versa, the fluid substance must follow a relatively long path and, in addition, it must overcome the resistance opposed by the membrane 6 which tends to resume elastically its initial shape.
- the flow of the substance through the channels 4 and 5 is therefore slowed down by the membrane 6. This is generally not a problem for emptying the container because, most of the time, we are rather looking for a controlled and relatively slow flow.
- the container 2 can be filled quickly, for example in an automatic filling chain, without it being necessary to increase the pressure of the substance which is injected into the container.
- the plug 1 may include a third channel 7, which extends obliquely in the spherical head 1b and in the cylindrical part 1a of the body of the plug.
- the channel 7 opens into the lower end face 1c of the cylindrical part 1a through an orifice 7a and, at its other end, into the upper half of the outer surface of the spherical head 1b through an orifice 7b.
- the elastic membrane 6 partially covers the bottom end face 1c of the cylindrical part 1a by forming a tongue 6a (FIGS. 5 and 6) which closes the orifice 7a of the channel 7, but does not block the orifice 4b of the channel 4.
- the tongue 6a of the elastic membrane 6 forms a second valve which allows flow in the channel 7 only from the outside of the plug 1 towards the inside of the container 2.
- the tongue 6a opposes the flow of the fluid substance a less resistance than in the case where the fluid substance is injected into the channel 5.
- the extent of the surface of the tongue 6a which must be deformed to allow the fluid substance arriving through the channel 7 to pass is smaller than the extent of the surface of the membrane 6 to be deformed between the orifices 4a and 5a to allow the fluid substance to pass from the channel 5 to the channel 4.
- the tongue 6a can be formed so as to have a smaller wall thickness than that of the membrane 6 in the region of the groove 3. Under these conditions, the container 2 can be filled more quickly through the channel 7 than through the channels 5 and 4.
- the plug 1 can be fitted with a movable cap which covers the spherical head lb of the cap and which hermetically seals the orifice 5b of the channel 5 as well as the orifice 7b of the channel 7 when the latter is present.
- the cap 8 which is shown in these figures and which can be manufactured by injection molding in a plastic material identical to that of the body of the cap 1, comprises a spherical cavity 9 ( Figures 10 to 12), which is slightly larger than a half-sphere and which has a radius
- the cap 8 has a nozzle 13, the internal channel 14 of which opens into the cavity 9
- the cap 8 On the side opposite to the nozzle 13, the cap 8 has an appendage 15 by means of which the cap 8 can be rotated relative to the spherical head 1b of the cap 1.
- the orifice 14a of the channel 14 is not in concordance with the orifice 5b of the channel 5 and the cap 8 therefore closes the port 5b.
- the cap 8 By applying pressure to the top of the appendix 15, for example by means of a finger of the hand, the cap 8 can be brought from the position 35 shown in FIG. 13 to the position shown in FIG. 14, in which port 14a of the canal 14 is in concordance with the orifice 5b of the channel 5, thus putting the channels 5 and 14 in communication with each other As can be seen in particular in FIGS.
- a cutout 16 is formed in the edge of the cap below the appendix 15, so as not to hinder the rotational movement of the cap 8 from the position of figure 13 to the position of figure 14.
- the bottom of the cutout 16 advantageously serves as a stop to define the limit position of rotation of the cap 8, in which the orifices 5b and 14a are entirely in agreement with one another. In this position, the contents of the container 2 can be evacuated from it through the channels 4 and 5 of the plug 1 and through the channel 14 of the nozzle 13. In this position of the cap 8, it is also possible fill the bottle 2 through the channels 14, 5 and 4.
- a spring element is provided to resiliently and automatically return the cap 8 to the position shown in FIG. 13 as soon as the pressure on the appendage 15 is stopped.
- the spring element may advantageously be constituted by a flexible rod 17, which is formed integrally with the body of the plug 1 and which extends radially in a recess 18 formed in the upper part of the spherical head 1b of the plug 1, the flexible rod 17 extends from the bottom of the recess 13 to a point close to the external surface of the spherical head 1b.
- the free end of the flexible rod 17 engages in a blind hole 19 formed in the bottom of the spherical cavity 9 of the cap 8, for example in a cylindrical boss 21 which protrudes radially, over a short distance, into the cavity 9 and in the recess 18.
- the flexible rod 17 and the hole 19 have a circular section.
- the cap 8 When the cap 8 is in one or the other 'other of the positions shown in Figures 13 and 14, the nozzle 13 and the appendix 15 are in the plane shown by the line VV in Figure 3.
- the cap S In the case where the channel 7 is provided, for filling the container the cap S must first of all be turned around the axis 10 of the cylindrical part la of the body of the stopper, which is also the longitudinal axis of the flexible rod 17, from the position shown in FIG. 13 until in a position in which the nozzle 13 and the app endice 15 are in a plane corresponding to the line VI-VI shown in Figure 3, a rotation of about 106 "in the example described here.
- the cap is brought into rotation on the spherical head 1b in a position similar to that shown in FIG. 14, but in this case the orifice 14a of the channel 14 comes into concordance with the orifice 7b of the channel 7, thus allowing the filling of the container through the channel 7.
- the flexible rod 17 brings the cap 8 back to a position similar to that shown in FIG. 13 so to close the orifice 7b of the channel 7.
- the two angular positions of the cap 8, which correspond respectively to the lines VV and VI-VI of FIG. 3 and in which the channel 14 of the nozzle 13 can be brought into line either with the channel 5, either with the channel 7 of the plug 1, can be defined by stops (not shown) provided on the plug 1 and / or on the cap 8.
- a protuberance can be provided on the plug 1 in a position such that 'it comes snap elastically into one of the slots 11 of the cap 8 when the latter is in the angular position corresponding to the line VV of Figure 3, and in another slot 11 of the cap 8 when the latter is in the angular position corresponding to the line VI-VI of Figure 3,
- another slot 11 may be provided in an angular position such that the cap 8 can be held in an intermediate position between the two angular positions corresponding to lines VV and VI-VI of FIG. 3, intermediate position in which the channel 14 of the nozzle 13 cannot be brought into concordance with either the channel 5 or with the channel 7.
- the recess 18 formed in the upper part of the spherical head 1b does not have a regular shape, but preferably comprises, seen from above (FIG. 3), a central part, which is cylindrical and in which the flexible rod 17 extends axially when it is not deformed, and two notches 18a and 18b which open radially into the central cylindrical part of the recess 18 in positions corresponding respectively to the lines VV and VI-VI of FIG. 3.
- the notches 18a and 18b have a width which is just a little larger than the diameter of the cylindrical boss 21 of the cap 8, so that the boss 21 and the flexible rod 17 can engage in one or the other of the notches 18a and 18b only when the cap 8 is in an angular position corresponding to one or the other of these two notches.
- a seal can be arranged around the orifice 5b and, if the channel 7 is present, also around the orifice 7b of this channel.
- the membrane 6 made of elastomeric material can also cover selected regions of the spherical head 1b of the plug 1, in particular around the orifices 5b and, where appropriate, 7b, so as to form the the aforementioned seals.
- the membrane 6 covers, at 6b, a spherical zone of the spherical head 1b, with the exception of the orifices 5b and 7b situated in this spherical zone.
- two circular beads 22 and 23 are protruding on the surface of the cavity 9 of the cap 8.
- the bead 22 surrounds the orifice 14a of the channel 14 and rests on the part ôb of the membrane of elastomeric material, around the orifice 5b of the channel 5, when the cap 8 is in the position shown in FIG. 14.
- the bead 23, located just above the bead 22, is arranged so as to s press on the part 6b of the elastomeric membrane, around the orifice 5b, when the cap 8 is in the position shown in FIG. 13.
- two other pairs of beads similar to the beads 22 and 23 can be provided to cooperate with the part ⁇ b of the membrane which surrounds the orifice 7b of channel 7 when the cap 8 is in one or other of the positions shown in FIGS. 13 and 14 and corresponding to the angular position represented by the line VV in FIG. 3, and to cooperate with the part 6b of the membrane surrounding the orifice 5b when the cap 8 is in the angular position represented by the line VI-VI in FIG. 3.
- the part 6b in the form of a spherical zone of the membrane of elastomeric material does not cover the entire spherical head 1b of the plug 1, but parts 24, 25 and 26 of said spherical head remain exposed in order to ensure a good guidance of the cap 8 in its rotational movements around the spherical head.
- Part 6b in the form of a spherical zone of the membrane is connected in one piece, by bridges of elastomeric material 27 and 28, to the part of membrane 6 which surrounds the cylindrical part 1a of the plug 1.

- the free end of the pin 29 is correspondingly widened and the pin 29 is split longitudinally so as to form two branches which are spaced apart from each other and which can be elastically deformed in order to allow the engagement of the pin 29 in the hole 31.
- the lengths of the parts of smaller diameter of the tenon 29 and of the hole 31 are chosen so that, after engagement of the tenon 29 in the hole 31, the upper wall 8a of the cap 8 is in sliding contact with the upper end face ld of the body la of the plug and that the cap 8 can rotate around the axis 10, without the possibility of axial movement along the axis 10, because of the shoulder 31a.
- the cap 3 has a nozzle 13 which, here, projects from the wall 8a of the cap 8.
- the channel 14 of the nozzle 13 extends parallel to the axis 10 and opens into the region of the upper end face ld of the body la by an orifice 14a which is eccentric with respect to the axis 10 with the same eccentricity as the orifice 5b of the channel 5.
- the orifice 14a of the channel 14 can be brought into concordance with the orifice 5b of the channel 5, in a single position of rotation of the cap 8, as shown in FIG. 17. In all the other positions of rotation of the cap 8, the latter hermetically seals the orifice 5b.
- the cap 8 comprises a cylindrical skirt 8b, which surrounds the neck 2a of the container 2 and which comprises, in its wall, at least two oblong openings 32.
- the two openings 32 extend in the circumferential direction of the skirt 8b and, in service, they cooperate with lugs 33 projecting from the outer surface of the neck 2a of the container 2.
- the lugs 33 have, seen in longitudinal section, a triangular profile defining a shoulder 33a which cooperates with the lower edge of the corresponding opening 32 of the skirt 8b for axially locking the cap 8 after its skirt 8b has been engaged around the neck 2a of the container 2.
- the lugs 33 also serve to limit the amplitude of the rotational movement of the cap 8 around the axis 10.
- the nozzle 13 may have a shape at least partially conical.
- the nozzle 13 can also serve as a nozzle for receiving a syringe needle.
- the skirt 8b of the cap 8 could be eliminated or greatly shortened.
- the orifice 5b of the channel 5 could be at the top of the spherical head 1b or in the middle of the upper end face ld of the body of the plug 1 and a nozzle similar to the nozzle 13 could be formed in one piece with the body of the plug, a small removable cap being able to be provided for closing off said nozzle.
